 CBRIS 2015, a Ukraine-U.S. co-hosted exercise, commences with an opening ceremony for the land component. Just the sheer fact that we're working together, there is so much to learn from each other. The friendships, the partnerships, it really is a fantastic opportunity to cement our commitment to the regional security here, but also to be able to work together with our partners. This is an opportunity to do just that. The exercise promotes regional security and cooperation between nations. Specialist Raul Pacheco, Shirokinan, Ukraine.
